Detailed explanation-1: -Photoperiodism is the physiological reaction of organisms to the length of night or a dark period. It occurs in plants and animals. Plant photoperiodism can also be defined as the developmental responses of plants to the relative lengths of light and dark periods.

Detailed explanation-2: -Photoperiodism is a plant’s response to the number of hours of darkness in its environment.

Detailed explanation-3: -Plant Physiology and Development Photoperiodism is the response to changes in daylength that enables plants to adapt to seasonal changes in their environment. The best studied example of photoperiodism in plants is flowering, but other responses to daylength include bud dormancy and bulb or tuber initiation.

Detailed explanation-4: -The main causes of photoperiodism are the interaction between the plant’s body and the light. The photoperiodic response can be reasonably predicted, but temperature, nutrition, and other environmental factors also alter the organism’s response.
